The Tiffen 77mm Neutral Density 0.9 Filter is a solid ND filter with an 8x filter factor that provides a 3 stop exposure reduction. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

0.9 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 3 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.

Filter does not affect coloration of the image and is ideal for use with other filters.

VERY GOOD for reduce brightness in VIDEOI use this Neutral Density 0.9 filters of ALL sizes with my Canon 5D Mark II and lenses in case to be able to filming on open aperture, wich is not possible in sunny days without it: in Photography we can reduce the shutter speed, but in VIDEO on 5D 2 cameras the minimum shatter speed is 1/60 second.. and any less that this is NOT RECCOMENDED! so we need to use ND filters, and I found that even 0.9 is not enough sometimes with fast lenses with 1.8, 1.4 and 1.2 aperture, so I've got also ND 1.5 filters .. AND THIS IS ONLY A WAY TO GET SHARP OBJECT ON BLURED BACKGROUND IN VIDEO on Canon 5D Mark II cameras!!

As expected but affects colour balanceThis ND filter does what it supposed to do but it has a significant warming effect. Some people might see this as an added bonus but it's a flaw in my opinion. I want to extend exposure time without having to correct colour tone in post processing. This filter is also not coated to shooting against light source (sun) will produce undesirable flare and ghosting effect. Unfortunately these flare effects are not pleasing such as those one might get from the lens alone but rather ugly harsh blobs which also have a warmer colour tone then the surrounding areas so fixing these in post is not easy. If you can afford it get a multicoated filter instead. Also 3 stops might not be enough so if you are trying to really blur water and clouds in daylight you will either need to stack to of these of you may want to opt for something like the 10 stop Big Lee Stopper.

green castThis filter has a great price, but it definitely has a very noticeable green cast. I tested it on my Sony FS700 video camera which has built in ND filters. On the FS700, with the ND filter wheel set to a 3 stop equivalent, there is no color shift. When using the Tiffen ND 0.9, there is a definite green shift. I tested this over and over again and all with the same results. You might ask: Why do I need additional ND filters if my video camera has them built in already? It's because on a bright day, the 6 stops of built in ND on my camera is not nearly enough for shallow focus shots.

amazing filter for an amazing pricethis is a great filter, the threads turn extremely easily and mount to my lens perfectly. the filter itself is made very well and keeps the colors true while stopping down light by 3 full stops. i use this to shoot moving cars in full daylight as well as waterfalls in daylight. i highly recommend this filter for anyone shooting rig shots. great filter, awesome price.

A Must Have FilterNeutral density filters are a must have item in any photog's bag. And Tiffen makes the best (okay, Singh-Ray has an awesome variable ND). Great and very useful piece of glass. No negatives to report. Allows for some artistic shots during full on daylight and just a great toll to reduce the volume of light in the shot. Buy several of these.

Shallow Depth of Field on a Wide Angle LThis filter allows me to open up to F2.8 in full daylight, giving me a shallow depth of field on my wide angle lens. When shooting video you are limited by shutter speeds so filters are the only way to block out light to accomplish this look. Did the job, Good Price.

Should have bought this awhile back.I've researched everywhere about buying the best ND filter for photos/videos. I just couldn't get myself to buy the ND Fader because of the slight softening effect. Typically if you need to shoot with a filter then your whole shoot will need a filter. If you change locations then just unscrew it. Unless you are jumping from an indoor low lit areas to the overexposed outdoors constantly then invest in a fader. If you have time to setup between each location then preserve the quality and get Tiffen ND.

Clear glassCurrently I have a strobe system that can over power the sun at f16 but I'd like to shoot at f5.6 or anything in between. I plan to shoot the everything in between by taking advantage of my cameras great ISO. This filter will help me effectively get a lower ISO to darken the sky. I will also be experimenting with video and keeping my shutter speeds low around 1/50. Up until now I had been using a plastic square filter but found them drop my resolution. I'd rather use glass and here it is.
